The distance from the earth to the sun is 1.496 x 1011 meters. the speed of light is 3 x 108 meters per second. show that correct to 3 significant figures, light will take 0.139 hours to travel from the sun to the earth

The time taken by light to travel from the sun to the earth is 0.139 hours and this can be determined by using the formula of speed.

Given :

The following steps can be used in order to show that light will take 0.139 hours to travel from the sun to the earth:

Step 1 - Remember in 1 hour there are 3600 seconds.

Step 2 - So, the speed of light in m/hour is:

m/hour

Step 3 - So, the time taken by light to travel from the sun to the earth is:

Step 4 - Simplify the above expression.

t = 0.139 hours

speed of light = 3 x 10^8 meters / second There are 3,600 seconnds per hour so,

speed of light = 3 x 10^8 meters / second * 3,600 = 1.08 x 10^12 meters / hour

1.496 x 10^11 meters ÷ 1.08 x 10^12 meters/hour = .1385 hours which rounds to

.139 hours  

Step-by-step explanation:

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
